Docs footer on pageReferences has problem

[WenjieDu]

Issue description

The footer display problem mentioned in #80 exists again. The problem seems to be related with docutils and sphinxcontrib-bibtex. Currently versions are Sphinx==6.2.1, docutils==0.19, sphinxcontrib-bibtex==2.5.0, furo==2023.3.27.

Refer to https://docs.pypots.com/en/test/references.html to see the mispresented footer, which should be at the page bottom but is on the right now.

One useful info, on my local machine, I install docutils==0.20, sphinxcontrib-bibtex==2.1.4 can help fix this issue, but failed on ReadTheDocs server.
